Given that Li batteries are packing enough power now to be considered unsafe and "explosive" in some cases, imagine what would happen if their capacity was increased 10 times. I've started thinking conservatively about battery capacity - it's the chips and software we should redesign, not only the batteries.

- Cushman 16y agoIf batteries are considered unsafe and "explosive", how do we rate gasoline?
- eru 16y agoOutside the movies, it's quite hard to get an explosion with gasoline. Total energy density isn't the only factor. And that applies to batteries as well.
- Cushman 16y agoSure, we wouldn't be using gasoline if it weren't already pretty safe. I'm just saying, before we call something dangerous, we should remember what the alternatives are.
- jfoutz 16y agoIf batteries could be 10x more powerful, you don't necessarily need to spend all the gains on longer duration. There is a space weight and power budget. Some of that budget could be spent on containment, or even just smaller more spread out cells.
- catch23 16y agoI'm not sure that increasing battery capacity is correlated with more explosive activity. These guys are using using the virus to increase surface area but the amount of lithium polymer may still remain constant so I don't think it will be more dangerous than the current line of lithium battery products.
- samatman 16y agoThe energy a battery is storing, in the event of an electrical short, is converted into heat. More energy, more heat. It's tough to work around this basic proposition of thermodynamics.
